N2 - The brittle phase in Sn-58Bi significantly degrades the reliability of electronic products. Doping effective element in Sn-58Bi solder is the common approach for improving the mechanical properties. In this study, the Bi ratio was decreased and minor In were doped depending on CALPHAD results. In addition, minor Ga was doped into the solder and formed the Sn-Bi-In-Ga quaternary system. The microstructure showed the Sn phase proportion was higher than Sn-58Bi solder and it is rich some amount of In and Ga. Moreover, Ga gathered in the micro-Area. In tensile test, the new solder showed high yield strength, tensile strength and much better elongation than Sn-58Bi solder.
